The hype continues: Obama campaign releases a video on Julian Castro’s life story

Five hours before the San Antonio mayor is scheduled to deliver the keynote speech at the Democratic National Convention, President Barack Obama’s re-election campaign released a 2 1/2 minute video previewing the “American Dream” theme of Castro’s speech.

The movie features the 37-year-old mayor and his twin brother, Texas state Rep. Joaquin Castro, along with his mother, Rosie Castro, who tells how she believes her family’s story “really is an American Dream story.”

The video includes family snapshots and trips down memory lane for the Castros.

“I’ve seen folks getting jobs, I’ve seen the economy picking up and the decision that Americans have to make is are we going to stay on that course, are we going to keep that American Dream, that opportunity to achieve that dream possible for all Americans,” he said. “That’s what this election is about.”

That’s the Democrats’ official teaser. For the rest, you’ll have to tune in at 9:05 p.m. CDT tonight.
